'I'his invention relates to calendars and particularly to the type of calendargwhichv includes a -block of separable sheets each having the date indications for a plurality of days, generally for the total number of days of the month, and which also comprises a date indicating device.

The' date indicating devices hitherto known and used in connection with calendars of the type referred to have consisted of a b-and or strip of celluloid or similar transparent material carrying a cursor in the shape of a distinctively coloured frame, and slidably secured around the block of sheets so that the band may be moved downwardly across said sheets and the cursor slid along the band so as to bring the frame over the date it is Adesired to indicate.

Such an indicating device has the drawback that as the sheets are removed from the calendar upon the expiry of the months the band surrounding the sheets becomes slack and tends to slide out of position.

Moreover, it has been found in practice that the adjustment of this indicating device is somewhat troublesome.

off the calendar.

The object of the present invention is to provide in a calendar of the type described, an improved type of indicating device, which comprises an arm of transparent material pivoted at one end to the card or base to which the calendar block is affixed and having its other end extending through an arcuate slot cut in the base, said strip carrying a cursor-frame slidable longitudinally thereof and being provided in the neighbourhood of that portion thereof which is in proximity to said arcuate slot, with a runner which loosely embraces the convex edge of the slot and thereby assists in holding the strip in position and guides the strip in its swinging movement.

The strip is preferably provided on its outer or exposed face with a small knob to facilitate manipulation. The pivoted end of the strip may be secured to the front or back of the base of the calendar.

In the latter event, a

second .arcuate slot is provided between the calendar block and the pivot, said second slot being concentric with the first or main slot and being intended to permit the strip to be brought over the front of the calendar so that it may overlie the calendar block. Both slots have their centre at the pivot.

In the drawing:

Fig. 1 is a plan of an indicating calendar in accordance with the present invention.

Fig. 2 is a section on the line II-II of Fig. l.

Fig. 3 is a plan of a slightly modified form of indicating calendar according to the present invention, and

Fig. 4 is a section along the line IV-IV of Fig. 3.

With reference to Figs. 1 and 2, the improved calendar according to the present invention comprises a base I0 on one face of which there is fixed as by means of staples` I2, a block I4 of tearoff sheets I5 each of which carries a plurality of dates corresponding to a month, for example, the dates of .all the days in the month. To enable the sheets to be torn off, a line of perforations I6, is provided.

In accordance with the present invention, the calendar is provided with an indicating device consisting of an arm I 8 of some transparent material, for example, Celluloid or the like, which is pivoted at one end to the base II) by means of a pivot 2E! preferably located below the block I4. The arm I8 overlies the block I4 and its other end 22 remote from the pivot 20 passes through an arcuate slot 24 formed in the base Ill, above the edge of the block remote from the pivot 20. Said slot 24 is an arc of a circle with its centre at the pivot 20. In the neighbourhood of its free end 22, the arm I8 carries a knob or button 26 to facilitate handling. This button is secured or formed on the exposed face of the arm I8 and is conveniently usedA to secure a runner device 28, which embraces the inner edge of the slot 24. If desired, said inner edge may be reinforced with a metallic binding as shown at 30, in Fig. 4.

The arm I8 likewise carries a cursor-frame 32 which is slidable longitudinally of the arm and serves to indicate the desired date.

In accordance with a modification illustrated in Figs. 3 and 4, the arm I 8 is pivoted to the rear face of the base I0 and a second arcuate slot 34 is provided concentric with the rst arcuate slot 24 but situated below the block I4. In this modification, the arm I8 is brought to the front of the base by passing it through the provided with the button 26 and runner 28.

Generally speaking, the monthly sheets of the calendar block in question are printed with the dates runing from left to right in number order. Consequently, with my improved type of calendar, it is a very simple matter to indicate the successive days of say, a week, it being necessary for this purpose merely to swing the arm I8 every day a few degrees about the pivot. When all the dates of one row have been passed, the cursor is slid down a sufficient distance for it to coincide with the next row and the arm is swung back to its extreme lefthand position. Conveniently, the rows of dates are arranged in arcuate bands as shown in Fig. 3 and the sheets are formed so as to decrease in width from the edge nearest the free end of the arm to the edge nearest the pivot.

I claim:

A calendar comprising a base, a block of tearoff calendar sheets secured to said base, each sheet bearing a plurality of dates, an indicating device comprising an arm of transparent material, a pivot for pivotally mounting one end of the arm on the face thereof remote from said block, an arcuate slot formed in said base on the side of said block remote from said pivot, a second arcuate slotl formed in said base between said block and said pivot, both said slots having a common centre at said pvot, said arm being threaded through said second arcuate slot, so as to overlie said block, the end of said arm remote from said pivot passing through the rst arcuate slot, a button secured to the exposed face of said arm in the neighbourhood of the end thereof remote from said pivot, a runner secured to the opposite face of said arm in the neighbourhood of said button, said runner embracing the convex edge of the rst slot, and a cursor-frame mounted on said arm for slidably moving longitudinally thereof.
